LB 24-270
Drilling rig

Liebherr’s drilling rig LB 24-270 is designed for the installation of different foundation piles. This includes Kelly drilling as well as various continuous drilling methods.
The machine can be transported with lowered leader system which enables a fast set-up time at the jobsite.
The LB 24-270 is driven by a powerful and at the same time consumption-optimized diesel engine. The high torque is achieved through the in-house developed rotary drive. The robust undercarriage provides an excellent stability. The leader can handle high torques and is also designed for high tractive forces of the rope crowed system. This allows for precise and fast drilling cycles.

Features

Easy transportation and quick set-up

Basic machine and leader with all hydraulic hoses connected can be transported in one piece. The minimized assembly work allows for quick and easy transportation of the machine between jobsites. Hence, time and money is saved even before operation starts.

Innovative crane control

The crane control system offers a multitude of programme and control options for various drilling methods. Service and machine data is also provided on color displays. The operator thus benefits from a facilitated handling of the rig. Hence, quick working cycles are achieved.

Innovative rotary drive

The hydraulic BAT rotary drive designed by Liebherr delivers the required torque for a wide range of drilling applications. The automated torque adjustment and the continuous speed optimization react flexibly to changing soil conditions – this guarantees an optimum crowd force.

Designed for challenging jobs

Drilling requires a robust and torsion resistant leader. Moreover, thanks to its unique parallel kinematics a large operating area is achieved, thus guaranteeing precise and solid working.
The telescopic undercarriage and the long crawlers offer a high level of stability.

Powerful drive technology

The Liebherr-own and fuel efficient diesel engine generates the required power. In combination with the on-board hydraulics a sufficient amount of performance for various deep foundation works is provided. When using further attachments like casing oscillators, no additional power pack is needed. more

High service availability

A global service network with experienced technicians and fast access to spare parts ensure high machine availability and a long product service life.

Optional equipment

Eco silent mode

With the eco silent mode the engine speed can be reduced to a predefined, required level. With this feature a notable reduction in diesel consumption can be achieved without any impact on operational output. Noise emissions are thus also lowered.

Automatic engine stop

The machine can optionally be equipped with an automatic engine stop control. Thanks to this feature it automatically switches off during longer work breaks after evaluating several machine parameters. This is fuel saving and environmentally friendly.

Low-head leader system

The automatic casing drive adapter with remote control for locking and unlocking the casing pipe offers significant advantages in terms of safety as no personnel is exposed to the hazardous area. In addition faster production cycles can be achieved.

Fleet management and teleservice

The data transmission and positioning system “LiDAT” provides important information on the operation of the machine. With these data the operation becomes more efficient. Various additional modules allow machine data reporting or access through service engineers via teleservice. more

Electronic evaluation of working processes

With the PDE process data recording system machine data is recorded during the working process. With PDR these data can be managed, displayed tabularly or graphically, and analyzed. In combination with the telematics system LiDAT these reports can be easily generated from the office.

Casing oscillators

If required, Liebherr piling and rotary drilling rigs can be equipped with a number of casing oscillators which are operated via the machine’s on-board hydraulics. No external power pack is required which leads to significant cost savings.
